Is the pressure drop through a globe valve less than through a gate valve?
HECK NO the globe pattern offers the most pressure drop because of friction losses
Does friction in pipes cause heat and pressure drop?
Simple answer: Yes.
What is pressure drop?
Pressure drop is a term used to describe the decrease in pressure from one point in a pipe or tube to another point downstream.This occurs when flow resistance resulting in frictional forces acts on the fluid while it is flowing through a tube. The major identifiers of the resistance include fluid viscosity and fluid velocity in the pipe. Pressure drop elevates the same way as shear forces inside the piping network. alliedallcityinc.com
What is theConstruction difference between stream turbine and gas turbine?
gas turbines and gas engines are different in mechanic designes uses diffrent liquid for engine we use flemmable gas we use for turbine liquide flemmable but they need air both gas turbines and gas engines are different in mechanic designes uses diffrent liquid for engine we use flemmable gas we use for turbine liquide flemmable but they need air both answer by nailiyoucef05@yahoo.fr I dont think so. Gas engine works as the same principle of a petrol engine. And in gas turbine gas is burned and high velocity gas is passed through the turbine. A gas engine is an internal combustion engine and have no turbines. alamm2@asme.org
Applications of orifice meter in industries?
(to check the flow rate of water ... calculate the pressure drop
What are the differences between an impulse turbine and a reaction turbine?
The difference between impulse and reaction turbine goes here...... 1) In case of an impulse turbine the pressure remains same in the rotor or runners, but in case of reaction turbine the pressure decreases in runners as well as stators also. 2) In case of impulse turbine the pressure drop happens only in the nozzle part by means of its kinetic energy. In case of Reaction one the stators those are fixed to the diaphragm act as a nozzle.
How do you decide number of stages for a steam turbine?
It is generally based on the Type of rotor ( Impulse/ curtis) and the enthalpy drop per stage.
What is difference bw condensing and non condensing steam turbines?
A condensing turbine uses all the energy from the steam going from high pressure turbine to secondary turbine to condensing turbine then sends the condensate back for reheating. where a non condensing turbine just uses the high pressure aspect of the steam then returns the low pressure stream back to be reheated. Condensng turbines utilises the entire available drop from high pressure to the vacuum in the condenser; a back pressure turbine only utilises only the top part, whereas an exhaust steam turbine utilises only th bottom part of the pressure drop. Hope that helps.
In blood vessels where does the greatest pressure drop occur?
the arterioles
Does there occur any change in melting point of ice by variation of pressure?
Yes, increase in pressure causes the freezing point to drop.
Why pressure drop occur even there was no leakage in hydrostatic test?
Isolating valves may have passing.
What should be the possible reasons of vacuum drop of turbine?
In the low pressure side of a steam turbine, the vacuum is maintained by the condensation of steam in the condenser. At high loads, the condenser may not satisify the demand, allowing steam to remain gaseous for a longer period of time. This can cause pressure to rise.
Does an industrial steam condenser work by a pressure drop?
From what I have read, it uses the heat of vaporization to create a vacuum due to condensation. So as steam condenses its volume is reduced. This creates a vacuum which increases the pressure drop accross the turbine. The larger the pressure drop accross the turbine, the better. I'm not an expert tho... http://books.google.com/books?id=7PeSdVhFhxgC&pg=PA41&lpg=PA41&dq=why+condenser&source=web&ots=HTeczt_DhL&sig=QS5YkcFzMQkTomz5y5FMb_Swsio&hl=en&sa=X&oi=book_result&resnum=1&ct=result
Why vacuum is created in condenser on steam turbine?
Firstly, vacuum is being created in turbine exhaust and condenser rather than being required. It is created to reduce the back-pressures and to improve the turbine efficiency. Also, with vacuum the designers can design large size last stage blades of LP turbine for maximizing the turbine output.
What is reheat factor?
It is the ratio of cumulative heat drop to isentropic heat drop in a multistage steam turbine.
Why do rockets drop there fuel tanks?
the efficiency of rocket propellant is called specific impulse the more the specific impulse the more the performance .
How did momentum and impulse affects the egg drop experiment?
Thats for me to know and you to find out.
